No, all shots were underground and fully contained with no venting in that time period.
It depends how long after the test. Surface testing has been banned for many years. I believe the original site of the first test in New Mexico in 1945 is accessible to the public. Sites of British tests in Australia in the 1950's are accessible, but I think you are advised not to stay for long, certainly not to live there anyway. More recent test sites are probably cordoned off by the military, though these have been underground tests some radiation may have leaked.
drinking water was unsafe
Nuclear power reactors are potentially dangerous, we have to make them safe by careful design and operation
robots
It is inherently greater than the importance of testing software for systems characterized by unsafe criticalness. :o
To see if the products being tested on them is okay for humans. But sometimes that is not the case, for example aspirin is toxic to rats and mice but not to humans.
No. Chernobyl is still contaminated with nuclear radiation, making this city unsafe to live in.
Hydrogen is an explosive gas in contact with oxygen and at high temperature.
no a chihuahua has to stick with dog food,its unsafe to try
If a nuclear weapon is set off not only will the area be destroyed completely the radiation will also spread around the world. (Depending how big the weapon was).
The atom bomb is a type of nuclear weapon. Nuclear weapons can kill entire cities, make air quality unsafe, and kill plants and animals.
Nuclear reactors themselves are usually safe, and they release no pollution into the air. The thing that makes the unsafe is the highly radioactive uranium rods and nuclear wastecreated by the reactors.
